DOUBLE HELIX describes the structure of the DNA
Answer:
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
Explanation:
Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.
Answer/Explanation:
Green plants can synthesise their own food by using light energy from the sun to convert carbon dioxide and water into glucose, with the release of oxygen. This process is called photosynthesis, and it occurs in specialized organelles called chloroplasts. The first stages of photosynthesis require light energy, and are often called the light-dependent reactions. The next stages occur in the absence of light energy, called the light-independent reactions.
In the light-dependent reactions, chlorophyll in the chloroplasts absorb light, converting into stored chemical energy in the form of NADPH and ATP. The high energy electron produced by light absorption travels down an electron transport chain, driving the pumping of hydrogen ions and creating a gradient. This provides the energy to produce ATP by ATP synthase
This process is used to provide for the light-independent reactions to form carbohydrates from carbon dioxide during a process called the Calvin cycle. The carbohydrates produced during photosynthesis are broken down during cellular respiration to generate ATP.
The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
C. Would be the best answer I guess. Hope that's correct!
